Questions 1 - 12
The technology of the North American colonies did not differ
strikingly from that of Europe, but in one respect, the colonists
enjoyed a great advantage. Especially by comparison with
Britain, Americans had a wonderfully plentiful supply of wood.
The first colonists did not, as many people imagine, find an
entire continent covered by a climax forest. Even along the
Atlantic seaboard, the forest was broken at many points.
Nevertheless, all sorts of fine trees abounded, and through the
early colonial period, those who pushed westward encountered new
forests. By the end of the colonial era, the price of wood had
risen slightly in eastern cities, but wood was still extremely
The availability of wood brought advantages that have seldom
been appreciated. Wood was a foundation of the economy. Houses
and all manner of buildings were made of wood to a degree unknown
in Britain. Secondly, wood was used as a fuel for heating and
cooking. Thirdly, it was used as the source of important
industrial compounds, such as potash, an industrial alkali;
charcoal, a component of gunpowder; and tannic acid, used for
The supply of wood conferred advantages but had some negative
aspects as well. Iron at that time was produced by heating iron
ore with charcoal. Because Britain was so stripped of trees, she
was unable to exploit her rich iron mines. But the American
colonies had both iron are and wood; iron production was
encouraged and became successful. However, when Britain developed
coke smelting, the colonies did not follow suit because they had
plenty of wood and besides, charcoal iron was stronger than coke
iron. Coke smelting led to technological innovations and was
linked to the emergence of the Industrial Revolution. In the
early nineteenth century, the former colonies lagged behind
Britain in industrial development because their supply of wood
led them to cling to charcoal iron.

The Peales were a distinguished family of American artists.
Charles Willson Peale is best remembered for his portraits of
leading figures of the American Revolution. He painted portraits
of Franklin and Jefferson, and over a dozen of George Washington.
His life-size portrait of his sons Raphaelle and Titian was so
realistic that George Washington reportedly once tipped his hat
to the figures in the picture.
Charles Willson Peale gave up painting in his middle age and
devoted his life to the Peale Museum, which he founded in
Philadelphia. The world's first popular museum of art and natural
science, it featured paintings by Peale and his family as well as
displays of animals in their natural settings. Peale found the
animals himself and devised a method of taxidermy to make the
exhibits more lifelike. The museum's most popular display was
the skeleton of a mastodon-a huge, extinct elephant-which Peale
unearthed on a New York farm in 180l.
Three of Peale's seventeen children were also famous artists.
Raphaelle Peale often painted still lifes of flowers, fruit, and
cheese. His works show the same luminosity and attention to
detail that the works of the Dutch masters show. In the late
eighteenth century, however, portraiture was the rage, and so
Raphaelle Peale found few buyers for his still lifes at the time.
His brother Rembrandt studied under his father and painted
portraits of many noted people, including one of George
Washington. Another brother, Rubens Peale, painted mostly
landscapes and portraits.
James Peale, the brother of Charles Willson Peale, specialized
in miniatures. His daughter Sarah Miriam Peale was probably the
first professional female portrait painter in America.

22. The author's attitude toward the Peales is generally
According to the best evidence gathered by space probes and
astronomers, Mars is an inhospitable planet, more similar to
Earth's Moon than to Earth itself-a dry, stark, seemingly
lifeless world. Mars' air pressure is equal to Earth's at an
altitude of 100,000 feet. The air there is 95% carbon dioxide.
Mars has no ozone layer to screen out the Sun's lethal radiation.
Daytime temperatures may reach above freezing, but because the
planet is blanketed by the mere wisp of an atmosphere, the heat
radiates back into space. Even at the equator, the temperature
drops to -50°C (-60°F) at night. Today there is no liquid water,
although valleys and channels on the surface show evidence of
having been carved by running water. The polar ice caps are made
of frozen water and carbon dioxide, and water may be frozen in
the ground as permafrost.
Despite these difficult conditions, certain scientists believe
that there is a possibility of transforming Mars into a more
Earth-like planet. Nuclear reactors might be used to melt frozen
gases and eventually build up the atmosphere. This in turn could
create a "greenhouse effect" that would stop heat from radiating
back into space. Liquid water could be thawed to form a polar
ocean. Once enough ice has melted, suitable plants could be
introduced to build up the level of oxygen in the atmosphere so
that, in time, the planet would support animal life from Earth
and even permanent human colonies. "This was once thought to be
so far in the future as to be irrelevant," said Christopher
McKay, a research scientist at the National Aeronautics and Space
Administration. "But now it's starting to look practical. We
could begin work in four or five decades."
The idea of " terra-forming" Mars, as enthusiasts call it, has
its roots in science fiction. But as researchers develop a more
profound understanding of how Earth's ecology supports life, they
have begun to see how it may be possible to create similar
conditions on Mars. Don't plan on homesteading on Mars any time
soon, though. The process could take hundreds or even thousands
of years to complete, and the cost would be staggering.

Another critical factor that plays a part in susceptibility to
colds is age. A study done by the University of Michigan School
of Public Health revealed particulars that seem to hold true for
the general population. Infants are the most cold-ridden group,
averaging more than six colds in their first year. Boys have more
colds than girls up to age three. After the age of three, girls
are more susceptible than boys, and teenage girls average three
colds a year to boys' two.
The general incidence of colds continues to decline into
maturity. Elderly people who are in good health have as few as
one or two colds annually. One exception is found among people in
their twenties, especially women, who show a rise in cold
infections, because people in this age group are most likely to
have young children. Adults who delay having children until
their thirties and forties experience the same sudden increase in
The study also found that economics plays an important role.
As income increases, the frequency at which colds are reported in
the family decreases. Families with the lowest income suffer
about a third more colds than families at the upper end. Lower
income generally forces people to live in more cramped quarters
than those typically occupied by wealthier people, and crowding
increases the opportunities for the cold virus to travel from
person to person. Low income may also adversely influence diet.
The degree to which poor nutrition affects susceptibility to
colds is not yet clearly established, but an inadequate diet is
suspected of lowering resistance generally.
35. The paragraph that precedes this passage most probably deals with
(A) minor diseases other than colds
(B) the recommended treatment of colds
(C) a factor that affects susceptibility to colds
(D) methods of preventing colds among elderly people

(A) It contains many inconsistencies.
(B) It specializes in children.
(C) It contradicts the results of earlier studies in the field.
(D) Its results apparently are relevant for the population as a whole.
38. It may be inferred from the passage that which of the following groups of people is most likely to catch colds?
(A) Infant boys
(B) Young girls
(C) Teenage boys
(D) Elderly women
39. There is information in the second paragraph of the passage to support which of the following conclusions?
(A) Men are more susceptible to colds than women.
(B) Children infect their parents with colds.
(C) People who live in a cold climate have more colds than those who live in a warm one.

42. The word "cramped" in line 21 is closest in meaning to
43. The author's tone in this passage could best be described as
About fifty years ago, plant physiologists set out to grow
roots by themselves in solutions in laboratory flasks. The
scientists found that the nutrition of isolated roots was quite
simple. They required sugar and the usual minerals and vitamins.
However, they did not require organic nitrogen compounds. These
roots got along fine on mineral inorganic nitrogen. Roots are
capable of making their own proteins and other organic compounds.
These activities by roots require energy, of course. The process
of respiration uses sugar to make the high energy compound ATP,
which drives the biochemical reactions. Respiration also requires
oxygen. Highly active roots require a good deal of oxygen.
The study of isolated roots has provided an understanding of
the relationship between shoots and roots in intact plants. The
leaves of the shoots provide the roots with sugar and vitamins,
and the roots provide the shoots with water and minerals. In
addition, roots can provide the shoots with organic nitrogen
compounds. This comes in handy for the growth of buds in the
early spring when leaves are not yet functioning. Once leaves
begin photosynthesizing, they produce protein, but only mature
leaves can "export" protein to the rest of the plant in the form
of amino acids.

(A) The relationship between a plant's roots and its shoots
(B) What can be learned by growing roots in isolation

47. The word "intact" in line 13 is closest in meaning to
48. The use of the phrase "comes in handy" in line 17 indicates that the process is
49. It can be inferred from the passage that, in the early spring, the buds of plants
(A) "export" protein in the form of amino acids
(B) do not require water
